Using Extension editor in Qlik Dev Hub

In the previous chapter, we discussed a recipe to develop a visualization extension in Qlik Sense by writing the code manually in the .js and .qext files. One of the easier methods to develop extension visualization in Qlik Sense is using Extension editor in Qlik Dev Hub.

A Qlik Dev Hub is an integrated development toolbox used for building visualizations and mashup websites. It does not come with a separate installation package, but the editor and the API libraries are provided with Qlik Sense Desktop.

The previous recipe has explained all the basics of the Dev Hub. This recipe will introduce the user to the process of building a basic chart extension using Extension editor in Qlik Dev Hub. The extension workbench supports the .js, .qext, .css, and .html formats.

Getting ready

For the purpose of this recipe,we will make use of an inline data load which gives the sales information for four countries:
